I still have a 4.0.4 bootloader on my S3's, never updated them, never flashed "full" Sammy ROMs using Odin (only CWM flashable ROMs without bootloader nor modem).

I'm back and I can tell you that even after upgrading the bootloader it still couldn't reboot. I also reverted back to stock, rooted that and still weren't able to reboot once an 4.3 based Rom was running. Seems like this is an issue that only appears to my s3. Even though we couldn't fix it (yet, perhaps), your help was much appreciated, yank!
